In each reaction box, place the best reagent and conditions from the list below. The result of these reactions will determine the type of molecule that is produced. Be sure to read the instructions carefully to ensure accurate results!

Reaction Boxes

Reaction 1.

A compound is made by placing a carbon atom in hydrogen, forming a complex molecule.

Reaction 2.

A compound is made by placing an oxygen atom in hydrogen and forming a complex molecule.

What is the Reaction?

The reactions will produce a variety of products. What is the reaction?

  1. Hydrolysis – Dilute hydrochloric acid (HCl) and add potassium ions until the desired pH is reached. This reaction produces H2O, Cl-, and free radicals.
  2. Oxidation – Add an oxidizing agent to a solution of silver nitrate (AgNO3). This reaction will produce silver ions (Ag+) and oxygen gas (O2).
  3. Reduction – Add a reducing agent such as sodium bisulfite (NaHSO4) to a solution of mercury(II) chloride (HgCl2). This reaction will produce mercuric ions (Hg-) and water vapor.

Best Reagent: What is the Best Reagent for this Reaction?

There are a lot of factors to consider when choosing a reagent for a chemical reaction. But in each reaction box, we’ve outlined the best reagent and conditions for each. So, whether you’re looking to create an acidic or basic solution, the best reagent for your needs is right below!

In general, acids are used to create solutions with lower pH levels, while bases are used to make solutions with higher pH levels. When reactants are combined in different ratios, they can produce over 1,000 different compounds!

Acidic Solutions: HCl (hydrochloric acid) is the best choice for an acidic solution because it has a high concentration of hydrogen ions. It also has a sour smell and can cause skin irritation.

Conditions: What are the Necessary Conditions for This Reaction?

The conditions for a reaction are essential for it to take place. In each reaction box, place the best reagent and conditions from the list below in order to achieve the desired result.


The temperature must be hot enough so that the reactants can react.


The reactants must be both soluble and reactive in order for the reaction to occur.


The solvent helps remove any impurities from the reactants so that they can react more easily.


Follow the directions carefully to ensure a successful reaction.

Results: What is the Outcome of This Reaction?

In each reaction box, place the best reagent and conditions from the list below. The outcome of this reaction is highlighted in green.

The best reagent for this reaction was potassium carbonate and the best conditions were 37 degrees Celsius and 100% humidity. The outcome of this reaction was black carbon.


In conclusion,all of these reagents and conditions will produce a positive result for the specific reaction being tested. Use these instructions to help you get started with your chemistry experiments!
